Controller unit failed after 18 months use.
Contacted Jason @ Kirby who was very helpful finding me a replacement unit.

Works as intended
Great if you want to keel your original brake levers.
I had to keep my original ones as the gear change and brake lever are integrated.
Works perfectly and easy to install.

Loving the Kirbebike 72V 4000W kit so far! It was easy to install and the power is insane—hits 55mph no problem. Battery range is solid too, perfect for long rides or daily commutes.

Great Upgrade for My E-Bike
I recently installed the Kirbe 72V-4000W High-Power E-Bike Kit, and I’m absolutely impressed with the performance! The upgrade was straightforward and everything was well packaged, with clear instructions that made the installation process smooth and easy.
The power output is fantastic – it really gives my bike a serious boost. The 72V battery provides a long-lasting charge, and the 4000W motor delivers incredible torque and speed, making uphill climbs and rough terrain feel like a breeze. I’ve been cruising at high speeds with minimal effort, and the acceleration is quick and responsive.
The build quality of the kit is top-notch, with solid components that feel durable and well-made. I've also noticed a huge improvement in the overall ride, and the kit seems to balance power and efficiency perfectly.
I’m really enjoying the ride and highly recommend this kit to anyone looking to upgrade their e-bike for more power and performance. Kirbe has definitely delivered on their promise of high-quality performance!

Fantastic Conversion Kit!
I recently installed the Mid-Motor Electric Conversion Kit on my bike, and I couldn't be happier with the results. The kit was easy to install, and the instructions were clear and straightforward. The mid-motor provides an excellent balance between power and control, making my rides smoother and more enjoyable.
I noticed a significant boost in performance, especially on hilly terrains. The motor is quiet, responsive, and the battery lasts a good amount of time even with regular use. It's perfect for both daily commutes and longer cycling trips.
The build quality is top-notch, and it feels incredibly sturdy. I’m really impressed with the overall performance and would highly recommend this kit to anyone looking to upgrade their bike to an electric one. This conversion kit truly exceeded my expectations!
